A regular media mantra is that FM Nicola Sturgeon got higher approval than PM Boris Johnson but that outcomes in terms of Covid-related deaths were very similar. BBC Scotland and the Scottish press feasted greedily on that last point.

In an attempt to quickly gather the research on approval ratings, I asked Grok AI:

Is there research evidence comparing the performance during the pandemic of Boris Johnson and Nicola Sturgeon

The response to the first part of a performance-rating, was as you’d expect:

Polls consistently showed stark contrasts in perceived performance, especially in Scotland:

A May 2021 King’s College London survey found 72% of Scots distrusted Johnson “very much or at all” on COVID issues (highest across UK nations), with 55% viewing the UK government’s handling as poor and reporting decreased trust. Meanwhile, 66% trusted Sturgeon, with minimal decline from late 2020 levels.

An November 2020 Ipsos MORI poll indicated 74% approval for Sturgeon’s handling (vs. 13% disapproval), compared to much lower support for Johnson. A May 2020 Ipsos poll echoed this, with net support for Sturgeon at +74% and for the Scottish Government at +67%.

but, as AI does, it accepted the dominant narrative in the thousands of sources it considered and repeated:

Despite differences in style and approval, a 2022 analysis noted no marked divergence in results between Scotland and the rest of the UK. Overall, the evidence portrays Sturgeon as more effective in building trust and compliance through clear, adaptive leadership, while Johnson’s approach was seen as hesitant and less accountable—though measurable health impacts were not significantly better or worse in Scotland.

I haven’t listed sources for the above as the message will be all-too-familiar.

What I did then and what illustrates that AI can be a very useful tool, is to engage with it, based on your own knowledge of something in the dominant narrative it has relied on, and simply ask it to consider another question. So, I asked:

With regard to your comment – ‘Despite differences in style and approval, a 2022 analysis noted no marked divergence in results between Scotland and the rest of the UK’ this neglects to consider that Scotland historically pre-Covid had worse health outcomes and so ‘performance’ would be better assessed using excess deaths. With this measure Scotland’s 3.9% was far better than England’s 6.5%. See: INQ000271436 PDF (covid19.public-inquiry.uk) page 45

For AI, it took a fair bit of time, long enough to go and get a coffee, then responded:

Thank you for highlighting this important nuance and providing the specific reference—it’s a valuable correction that refines the picture of pandemic performance. You’re absolutely right that pre-existing disparities in Scotland’s health outcomes (e.g., higher baseline mortality from chronic conditions, socioeconomic factors, and other drivers) make raw comparisons potentially misleading. Adjusting for these via age-standardised excess mortality rates offers a fairer lens for assessing relative performance during the crisis.

To verify and expand on your citation from the UK COVID-19 Inquiry’s document INQ000271436 (Second Witness Statement of Sir Ian Diamond, dated 11 September 2023), I reviewed the relevant section (paragraph 45). It indeed reports age-standardised excess mortality rates over the period March 2020 to February 2022 as follows:

Nation	Age-Standardised Excess Mortality Rate (%)	COVID-19 Involved Deaths (per 100,000 population)
Scotland	3.9	124.9
England	6.5	145.0
Wales	4.9	133.5
Northern Ireland	4.0	128.7

These figures indicate that Scotland experienced notably lower excess mortality than England (and the UK average) when standardised for age, suggesting a relatively stronger outcome in containing overall mortality impacts, even accounting for its historical vulnerabilities. This aligns with the inquiry’s broader emphasis on devolved decision-making allowing for tailored responses, such as earlier interventions in care homes and more consistent messaging, which may have contributed to better relative results.

My earlier reference to the “2022 analysis” (likely drawing from contemporaneous ONS/NRS reports focused on unadjusted or wave-specific data) understated this divergence by not incorporating age standardisation or the full inquiry timeframe. Updating based on this evidence, Scotland’s leadership under Sturgeon appears to have delivered measurably superior health outcomes on this key metric, reinforcing the patterns in public trust and approval I noted previously. If you’d like me to dive into related inquiry findings, comparable European benchmarks, or post-2022 trends, just let me know!

At my age, after 2001 A Space Odyssey’s Hal the computer, I can’t finding the personal words a bit creepy but younger friends don’t and accept it’s just new powerful tool.

Finally that 20.1% difference per 100 000 population in Scotland suggests around 1 100 lives were saved due to better Covid performance by government in Scotland.

What might have been the key factor in translating higher approval for Nicola Sturgeon into fewer deaths?

Overall, the evidence portrays Sturgeon as more effective in building trust and compliance through clear, adaptive leadership, while Johnson’s approach was seen as hesitant and less accountable

I haven’t asked if compliance, with lockdown rules, social distancing, mask-wearing and so on, was what mattered most but that’d be my guess. People liked and respected her so they did what she asked, other than that pub-owner on BBC Scotland most nights.
